PECIFCATION forming part of Letters Patent No. 456,736, dated July 28,1891.

Application filed October 1 l, 18 8 9.

T0 all whom t may concern.:

Be it known that I, LOUIS SCHULTZ, of New York, in the county and Stateof New York, have invented a certain new and useful Improvement inQuiltingMachines, of whiclf the following is a specification.

I will describe a quilting-machine embodying my improvement, and thenpoint out the novel features in the claims.

In the accompanying drawings, Figure l is a back view of a machineembodying my irnprovement, certain parts being broken away to economizespace. Fig. 2 is a plan or top view of the machine, certain parts beingrepresented in section. Fig. 3 is a transverse vertical section taken atthe plane of the doited line x or, Fig. l, and looking in the directionindicated by the arrow which is contiguous to such line. Fig. 4f is atransverse vertical section taken at the plane of the dotted line y y,and looking in the direction indicated by ,the arrow which is contiguousto such line. Fig. 5 is a horizontal section of a portion of themachine, taken at the plane of the dotted line Fig. l. Fig. 6 is atransverse vertical section corresponding generally to Fig. 4, butillustrating a modified construction. Fig. 7 isa section ofthe partsillustrated in Fig. 6, taken at the plane of the dotted line w w, Fig.6. Fig. 8 is a face view of a piece of quilted fabric which may beworked in this machine.

Similar letters of reference designate corresponding parts in all thefigures.

A designates the bed of the machine. As here shown, it is supported onlegs A. On the bed is mounted a table A2, the latter being slightlyelevated.

B B2 designate two side frames secured in the present instance to thetable A2 by bolts orotherwse to occupy parallel positions. 3etween themextends a cross-bar or stretcher It is obvious that the table A2 can be`dispensed with if the side frames B B2 are extended downwardly toconnect with the bed A.

C designates the needle-bar. This has secured to it a series of needlesO', which, in the present instance, are arranged in two rows, so thatthe needles of the second row will be behind those of the first row andopposite the Serial No. 326.671. (No modeL spaces between those of thefirst row. This arrangement of the needles maybe understood by referenceto Figs. .l and 3, where some of the needles are represented, and italso may be understood by reference to the zigzag row of circles, whichin Fig. 2 represent holes in the cover of the shuttle or loop chamber.

Secured to the needle-bar are a number of upright rods c, which workvertically within brackets b, attached to the front of the bar C, andare connected at the upper end by links c with arms c2, affixed toarock-sl1aftO2. On the rock-shaft are other arms c3, and these areconnected with rods c4, secured to a presserfoot bar. The rock-shat`t isoscillated by means of a rod O3 deriving motion from a crank c4,arranged upon a shaft D. It will be readily understood that thercckshatt imparts a vertically-reciprocating motion to the needle-barand needles. The needles in this machine have only an up-anddownmovement.

In the machine is included shuttle mechanism, and E designates therace-bar therefor.

In the present example of the improvement the fabric to be quilted isfed lengthwise under the needles, and also moved laterally. Rollers F F2serve to move it longitudinally. These rollers are supported in acarriage G G2 G3. frames G G2 and rods G3 securing them together. It isfree to move in any direction in a horizontal plane. As shown, theseside frames G G2 have secured to them rollers R', extending widthwise ofthc machine parallel with the needle-bar, and journaled in bracketsfastened to the lower extremities of the Side frames. Beneath theserollers R' are pairs of rollers R2,extending forwardly and backwardly ofthe machine and journaled in brackets secured to the bed A. The rollersR rest upon and are supported by the rollers R2. It will readily beunderstood that the rollers R may roll upon the rollers R2 in thedirection of the axes ot lthe latter, so as to enable the carriage tomove backwardly and forwardly, and that the rollers R2 can rotate underthe rollers R', to enable the carriage to move laterally, or, in otherwords, lengthwise of the needlebar. Thewfeed-roller F is This carriageconsists of two side i IOS journaled in the side frames G G2 of thecarriage. Theroller F2 is journaled in levers G4, which are fulcrumedbetween their ends by pins or bolts g to the side frames G G2 of thecarriage. At the rear ends the levers G4 are connected to springs G5,attached to screws G, engaging with upright bars fast.- ened to the sideframes of the carriage. These springs force the roller F2 with greateror less pressure toward the roller F.

The fabric to be quilted is at first rolled o'n a roller R, attached tothe carriage. Thence it is drawn by the feed-rollers over an apron P,extending beneath the needles and attached to the carriage.

The feed-rollers F F2 are geared together by gear-wheels f, affixed totheir journals at one end. To the rollers F is affixed a gearwheel f2.The gear-wheel f2 derives motion from a gear-wheel f3, affixed to ashaft F, which is supported at one end in the side frame B2 of thecarriage. l

The shaft F does not partake of the lateral movement of the carriage.Hence there must be a relative sliding movement between it and thecarriage. Because of this the vgear-wheel f3 is to be secured to theshaft F by means of a spline or feather and connected to the bearing ofthe carriage receiving the shaft F, so that the gear-wheel will movewith the carriage and have a sliding movement relatively to the shaft F.The shaft F is connected by a universal joint f4 to a shaft F4. rIhisshaft F4 is supported in bearings f4", supported by the bed A of themachine.

Owing to the universal joint between the shafts F and F4, the carriageis able to move forwardly and backwardly. It is therefore possible forthe carriage to move in any and all directions in a horizontal planewithout interfering with the transmission of rotary motion to thefeed-rollers. The shaft F4 has affixed to it a gear-wheelf, derivingmotion periodically from a tooth ed segment f7, affixed to a shaft F5.This shaft F5 is supported in one of the bearings On this shaft F5 isaffixed a bevel gear-wheelf44, which engages with a bevel gear-wheelf42, affixed to an upright shaft F, journaled in a bracket flo, erectedon the bed A. The shaft has affixed to it a worm-gear fw, which derivesmotion from a worm f44, affixed to the driving-shaft D. The shaft F5,therefore, moves constan tl y with the driving-shaft. It transmitsmotion to the shaft F4 and thence to the feed-rollers periodically,owingto the fact that no motion is transmitted to the shaft F4 except whenthe toothed segment engages with the gear-wheel f6. On the shaft F4 isaffixed a lock-wheel fm, coacting with a stop fiange or disk fg, affixedto the shaft F45. The stop flange or disk ff is circular in form, buthas a notch or opening iu its periphery. Except when this notch comesopposite the lock-wheel f4", the stop flange or disk engages with thelock-wheel f45 and holds the latter against rotation.

sense Vhile the shaft F4, carrying this lock-wheel, is thus held againstrotation the feed-rollers are precluded from rotating. One end of thenotch or opening in the stop fiange or disk one end lof the toothedsegmentj1T enters into engagement with the gear-wheel f on the shaft F4,and the notch or opening is not carried beyond the lock-wheel untilafter said toothed segment has gone out of engagement with the wheel f6.It follows, therefore, that the stop liange or disk locks the shaft F4and thefeed-rollers at all times, except when the toothed segment f7engages with the wheel f to rotate the shaft F4 and the feed-rollers. Onone of the journals of the roller F maybe affixed a pulley H to enablethe roller to transmit rotary motion to a roller upon which thecompleted fabric will be taken up or wound. I-Iaving now described themechanism by 'which rotary motion is imparted to the feedrollers andexplained the motions imparted to which are here employed for producingthe motions to the carriage.

I designates an upright shaft supported from the bed A and havingaffixed to it a cam I. This cam operates in conjunction with two bars orplates I2 I3, fitted to slide in bearings and provided with bowls orrollers The bar or plate I2 is connected to a bar G7, secured to thecarriage G G2 G3 by means of a bolt engaging in a slot in said bar,andthis bar or plate extends lengthwise of the machine. It will be obviousthat the carriage will be moved laterally by the action of the cam Iupon the bar or plate I2. The bar or plate I3 is provided with a toothedrack t3, which engages with a toothed segment I5, affixed to a shaft I4,journaled in bearings supported by the bed A. The shaft I4 has affixedto it two toothed segments I5, and these engage with toothed racks IG,secured to the carriage G G2 G3. It will be obvious that whenever thecam I imparts a movement to the bar or plate I2, this motion will betransmitted to the carriage and will cause the car riage to movebackward and forward.

The cam I', it will be seen, serves to produce a movement of thecarriage in two different directions, and these combined movements willresult in a movement of the carriage in a circular or other sinuouspath. By varying the cam the movement of the carriage will be varied. Itwill be seen that the cam is stepped and that the bars or plates 1213are longitudinally slotted to embrace the shaft I. The stepping of thecam is not, however, essential and the bars or plates may be madedifferently. The shaft I is shown as having affixed to it a gear-wheeli444, which engages with a worm f25, affixed to the shaft I).

I have now explained the motions of the feed-rollers and the movementsof the carriage necessary for the production by each needle of a circleof stitching. I willnow describe a mechanism whereby the operation ofthe carriage, I will now describe the meansv comes opposite thelock-wheel f15 just before Y IOO the needles and shuttle will betemporarily suspended to enable the fabric to be fed a certain distancepreparatory to the quilting upon is connected by a link j with an arm J3, affixed to a rock-shaft j', which is j ournaled in brackets or standserected upon the bed A. The rock-shaft has atlixed to it arms J4, whichare provided with bowls or rollers entering a circumferential groove ina sleeve J 5, which fits upon the shaft D This sleeve is free to bemoved lengthwise of the shaft D; but it is locked to rotate with theshaft D by means of a feather or spline. This sleeve has affixed to itone part of a clutch. In the present instance it is shown as having thefemale part J6 secured to it. The other part J7 of the clutch is securedto the shaft D The clutch may be of any suitable construction. In thepresent instance the female part consists of an infernali y-conical Hange, and the male part is circumferentially conical to engage with saidflange. The male part is shown as being provided with a projection f,arranged in such position that on the rotation of the driving-shaft Dafter the engagement of the two parts of the clutch it will encounterthe shoulder of a projection j, with which the female part is provided'.The object of these projections is to insure the positive engagement ofthe driving shaft D with the shaft D. Lest the purpose of this clutch isnot apparent, I will explain that whenever the parts of feed from thefront to the back of the machine,

pivotally connected a rod K.

which is indicated by the straight full lines in Fig. 8. It will beunderstood that the cams J J 2 effect the disconnection of the shaft Dfrom the driving-shaft D once in every rotation of the upright shaft F,which carries the cams. To one of the arms J 4, which serves to effectthe shifting of the female clutch Ji, is The rod K is pivotallyconnected to the upper end of a lever K', which is fulcrumed at thelower end to a stand K2, erected on the bed A. The upper end of thislever K is forked to embrace the hub of a non-rotary disk Ki", fitted toslide lengthwise of the shaft D. The lever K may connect with the hub ofthe disk K'" by means of pins extending from the lever into cavities orrecesses in the hub of the disk. The disk K3 has in its periphery arecess, into which extends the end of a rod 15, whereby the disk will beprevented from rotating. The recess is sufficiently long in thedirection of the axis of the shaft D to allow of the necessary slidingmovement of the disk axially of said shaft.

It will be seen that whenever the arms J 4 move the female part of theclutch away from the male part the disk K3 will be correspondin glyshifted toward a disk K", which is aflixed to the shaft D to rotate withit. The disk Kg on the side next the disk K4 is preferably faced withleather, as its purpose is to act as a brake or stop for the shaft D. Onthe disks K3 K4 are shouldered projections l 2, similar to theprojections jj, heretofore described. They will prevent any slipping ofthe disk K4 relatively to the non-rotary disk K3 after the disk K'i hasin rotating assumed a certain relation to the disk K3, but it isintended that the brake Ki5 shall previously thereto have graduallyarrested the rotary movement of" the disk K4 and shaft D.

The driving-shaft D', it will be noticed, is provided with fast andloose pulleys. On the shaft D is loosely mounted an arm L, carrying apawl L', which operates in conjunction with a ratchet-wheel L2, affixedto said shaft D. By oscillating the arm L the shaft D may be rotated byhand to adjust it in any desired position.

As shown in Figs. 6 and 7, the toothed segment f7, from which theintermittent rotary motions of the feed-rollers are derived, has thatone of its teeth t which enters the IOC gear-wheel f6 made capable ofyielding, so

that if it should not enter properly it would be free to yield and movegradually into proper position without suffering injury. rlhis tooth tis provided with a bifurcated shank embracing the body or disk of thesegment f7 and extending radially thereon. The two arms of thisbifurcated shank preferably fit in grooves formed radially in the bodyor disk of the segment f7. This tooth is capable of moving in a radialdirection inwardly and outwardly. Its outward: movement is limited by astop-pin t', which is secured to the body or disk of the segment f7, andextends in the path of a projection t2, with which one of the arms ofthe bifurcated shank of tooth t is provided. A lever t3, fulcrumedbetween the ends by a pin or screw t* to the body or disk of the segmentf7, is at one end i pivotally connected with the shank vof the tooth t,and at the other end is connected with a spring The spring t, actingthrough the lever, tends to force the tooth t outward. The tooth t may,however, move inward against the resistance of the spring. Preferablythere will be a lever t3 and spring t5 on each side of the body or diskof the segment f7, and combined with each one of the bifurcated arms ofthe shank of the tooth t.
